Docker for Mac - mkmf.rb cannot find header files for ruby

Question

I updated Xcode on my Mac and since then, when starting Docker with, docker-sync-stack startI get this error message:

mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/include/ruby.h

I tried installing ruby ​​with this: brew install rbenv ruby-buildbut that doesn’t change anything.

Does anyone know how I can fix this?

Thank!

Answer 1

When upgrading Xcode, you need to install the command line tools and additionally accept the conditions:

sudo xcode-select --install

Then:

sudo xcodebuild -license

:

Mac OS X 10.14 stopped putting inclusion libraries in their usual location, / usr / include, saving them only inside the Xcode directory.

To confirm that this is a problem, simply run ls /usr/include. If the result is empty, this is really a problem.

Apple supplies the "obsolete installer" so you can install the Headers in the "old place." To solve the problem, just run this:

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
